3 Claims.

The present invention relates to new and useful improvements in oilburners and more particularly to a conversion oil burner for installingin wood burning heating stoves.

An important object of the invention is to provide an oil burner whichmay be easily and quickly installed in a conventional wood burningheating stove without necessitating any changes or alterations in theconstruction thereof to convert the stove to the burning of oil.

A further object of the invention is to provide float control fuelsupply means for the burner together with means for regulating the levelof the liquid maintained in the burner.

A still further object is to provide a device of this character ofsimple and practical construction, which is efficient and reliable inoperation, relatively inexpensive to manufacture and other- WiSe welladapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view of a stove with the oil burnerinstalled therein.

Figure 2 is a side elevational view showing the support for verticallyadjusting the float chamber.

Figure 3 is a transverse sectional view taken substantially on a line 33of Figure 1.

Figure 4 is an enlarged fragmentary vertical sectional view taken on aline 4-4 of Figure 2.

Figure 5 is an enlarged horizontal sectional view taken on a line 55 ofFigure 4, and

Figure 6 is a vertical sectional view taken on a line 6-6 of Figure 5.

Referring now to the drawings in detail wherein for the purpose ofillustration I have disclosed a preferred embodiment of the inventionthe numeral 5 designates a conventional heating i3 welded or otherwisesuitably secured to the underside of the ring to support the combustionchamber in a suspended position from the ring. The walls of thecombustion chamber are perforated as shown at I4 to provide thenecessary air draft for combustion purposes, the combustion chamberextending downwardly below the flange l and spaced inwardly from thewalls of the collar l i.

stove which includes a combustion chamber 6 at the lower portion ofwhich is an internal annular flange '1 for normally supporting a grate(not shown) thereon for burning solid fuel, such as wood in the stove.An ash pit 8 is provided below the flange l and provided with a door 9having a conventional draft opening l0 therein.

The conversion oil burner forming the subject 2 of the present inventioncomprises a supporting collar ll resting on the flange 1 with a ring [2resting on its upper edge and having a substantially cup-shaped oil potor combustion chamber An annular partition if is positioned in thecombustion chamber l3 with a central opening 16- therein, the partitionforming a fuel chamber il in the lower portion of the combustion.

chamber.

A fuel supply pipe I8 is connected to the lower portion of the fuelchamber I! and extends outwardly through an opening IS in the ash pit Bof the stove, the outer end of the pipe l8 being connected to a floatchamber 20 by flexible tubing 2!. A flexible tubing22 is also connectedto the bottom of the float chamber leading from a suitable source ofsupply and positioned in the float chamber is a conventional floatcontrolled valve (not shown) to regulate the level of liquid admitted tothe float chamber.

A substantially yoke shaped slide 23 is suitably secured to the floatchamber 2|! for vertical sliding movement on a vertical supporting rod24 having its ends welded orotherwise suitably secured to an upstandingbracket 25 secured to the base portion of the stove 5 by a flange 26 andbolts and nuts 21.

A lever 28 is pivoted in an lever toward the right the float chamberWill be 7 raised, fuel from the float chamber being supplied by gravityto the fuel chamber ll of the burner and the raising and lowering of thefloat I chamber thus regulating the level of liquid in the fuel chamberI1.

The float chamber 20 is held in its raised position by a rounded button33 past which the lever 28 is moved to hold the lever against loweringmovement.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of thedee opening 29 in the V bracket 25 and is formed with a crank 30 at its1 vice will be quite apparent to those skilled in the art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A conversion oil burner for stoves having an internal annular flangeand comprising a burner pot supported on the flange, .a feed line forthe pot, and liquid level control means for the pot and including afixed bracket, a guide rod on the bracket, a float chamber connected tothe feed line and including a yoke vertically slidable on the guide rodand coacting with said bracket to prevent the float chamber from turningon said rod, and a lever pivoted on the bracket and connected to theyoke for raising and lowering the float chamber.

2. A conversion burner for a stove comprising a burner pot for liquidfuel supported in the stove, and liquid level control means for the potincluding a fixed bracket, a vertical guide rod on the bracket, a floatchamber comprising a yoke vertically slidable on the guide rod andcoacting with said bracket to prevent the float chamber from turning onthe rod, and a lever pivoted on the bracket and connected to the yokefor sliding the same to raise and lower the float chamber.

3.11 conversion oil burner for stoves, having an internal annular flangeand comprising a burner pot supported on the flange, a feed line for thepot, and liquid level control means for the pot including a fixedbracket, 2. guide rod on the bracket, a float chamber connected to thefeed line and including a yoke vertically slidable on the guide rod andcoacting with the bracket to prevent the float chamber from turning onthe rod, and means mounted on the bracket and connected to the yoke foroperation to raise and lower the float chamber.
